Problems solved by technology

[0012] The horizontal articulated robot of Patent Document 1 has the following problem: when the first arm and the second arm are horizontally rotated, since the second motor is provided on the front part of the first arm, the second motor is provided on the front part of the second arm. The 3rd and 4th motors increase the weight of the arm and further increase the moment of inertia, making it difficult to transport the work at high speed

Embodiment Construction

[0035] Hereinafter, examples of the present invention will be described with reference to the drawings, but the present invention is not limited to these examples.

[0036] exist Figure 1 to Figure 5 A conveying device 100 as an embodiment of the present invention is shown in . The transport device 100 includes the first arm 121 , and can perform the swiveling motion and the linear motion of the first arm 121 . An output shaft 124 is connected to the front end of the first arm 121, and the output shaft 124 grips (picks up) a workpiece (work object) at the other end opposite to the end to which the first arm 121 is connected. Motion and / or straight-forward motion to convey, configure (place) workpieces. Moreover, the conveyance apparatus 100 is equipped with the 2nd arm 122 for supporting the output shaft 124, and is equipped with the bearing 123 so that the output shaft 124 may perform a smooth linear motion. The conveying device 100 includes: a rotary motion mechanism 101...

Abstract

Provided is a conveyance device capable of achieving high-speed conveyance of a workpiece through arm weight reduction and inertial moment reduction. The conveyance device (100) capable of rotating and linearly moving an arm (121) comprises: a rotary motion mechanism (101) which has a first rotary shaft (108) capable of rotating about a first axis (103); a rotation transmission mechanism (109) which is connected to the first rotary shaft (108) and is capable of rotating the arm (121) when the rotation transmission mechanism (109) is caused to rotate about a second axis (106) in response to rotation of the first rotary shaft (108); and a linear movement mechanism (104) which is capable of linearly moving the arm (121). The linear movement mechanism (104) is disposed on the inner side of therotation transmission mechanism (109) in such a manner as not to rotate in response to rotation of the first rotary shaft (108).

Description

technical field [0001] The present invention relates to a conveying device and a pick-and-place device capable of conveying a workpiece (workpiece) at high speed and capable of turning and / or straightly advancing the workpiece to an arbitrary position. Background technique [0002] Various conveyance devices have been proposed in which workpieces can be taken in and out by using a drive source such as a motor to make an arm swing and / or linearly move. [0003] Patent Document 1 discloses a 4-axis horizontal articulated robot (SCARA robot), which has: a first arm that rotates horizontally around a first axis by a first motor; a second arm that is connected to the first arm The front part of the arm is rotated horizontally around the second axis by the second motor; and the shaft, which protrudes vertically downward from the front part of the second arm, moves up and down along the third axis direction respectively by the third and fourth motors, and rotates around the second ...
